MYSQL選擇表行，其中列在我的代碼中的多個記錄中包含相同的數據

Question

我在這里有一個mysql代碼-

$querymypm = "SELECT * FROM pm WHERE recieverun='$uname' AND senderun='$c' ORDER BY pmid DESC";

但我想要這樣-

$querymypm = "SELECT * FROM pm WHERE recieverun='///(Taking more than one value)///' AND senderun='///(Taking more than one value)///' ORDER BY pmid DESC";

Answer 1

使用IN運算符。

$querymypm = "SELECT * FROM pm WHERE recieverun IN ('$uname1', '$uname2', '$uname3') AND senderun IN ('$c1', '$c2', '$c3') ORDER BY pmid DESC";
